Where: Wilbarger County, Texas (34.0° N, 99.2° W: paleocoordinates 2.5° N, 28.6° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Arroyo Formation (Clear Fork Group), Kungurian (279.3 - 272.3 Ma)
• "above the Lueders limestone, and quite probably correspond to the beds to the south of Coffee Creek." Details for Faunal Zone 4 of Romer 1928: "The vertebrate remains are confined to approximately the lowest 250 feet or so of the Clear Fork.."
•the base and top of the Clear Fork Group (i.e., Arroyo, Vale, and Choza formations) are both within the Kungurian: see Wardlaw 2005 (Permophiles) for the base, and DiMichele et al. 2001 (J Paleont) for the top
• group of beds-level stratigraphic resolution
Environment/lithology: terrestrial; red claystone and conglomeratic sandstone
Size class: macrofossils
